xmlcreate
Overview
xmlcreate is a Node.js module that can be used to build XML using a simple API.
Features
xmlcreate allows you to use a series of chained function calls to build an XML tree.
Once the tree is built, it can be serialized to text. The formatting of the text is customizable.
xmlcreate can perform some basic validation to check that the resulting XML is well-formed.
Installation
The easiest way to install xmlcreate is using npm:
npm install xmlcreate
You can also build xmlcreate from source using npm:
git clone https://github.com/michaelkourlas/node-xmlcreate.git
npm install
npm run-script build
The build script will build the production variant of xmlcreate, run all
tests, and build the documentation.
You can build the production variant without running tests using the script
prod. You can also build the development version using the script dev.
The only difference between the two is that the development version includes
source maps.
Usage
The documentation for the current version is available here.
You can also build the documentation using npm:
npm run-script docs
Examples
The following TypeScript example illustrates the basic usage of xmlcreate:
import {document} from "xmlcreate";
const tree = document();
tree
.decl({encoding: "UTF-8"})
.up()
.dtd({
name: "html",
pubId: "-//W3C//DTD XHTML 1.0 Strict//EN",
sysId: "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
})
.up()
.element({name: "html"})
.attribute({name: "xmlns"})
.text({charData: "http://www.w3.org/1999/xhtml"})
.up()
.up()
.attribute({name: "xml:lang"})
.text({charData: "en"})
.up()
.up()
.element({name: "head"})
.element({name: "title"})
.charData({charData: "My page title"})
.up()
.up()
.up()
.element({name: "body"})
.element({name: "h1"})
.charData({charData: "Welcome!"})
.up()
.up()
.element({name: "p"})
.charData({charData: "This is some text on my website."})
.up()
.up()
.element({name: "div"})
.element({name: "img"})
.attribute({name: "src"})
.text({charData: "picture.png"})
.up()
.up()
.attribute({name: "alt"})
.text({charData: "picture"}).up().up().up().up().up();
console.log(tree.toString({doubleQuotes: true}));
This example produces the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>My page title</title>
</head>
<body>
<h1>Welcome!</h1>
<p>This is some text on my website.</p>
</body>
</html>
A JavaScript version of this example can be found in the examples directory.
Tests
xmlcreate includes a set of tests to verify core functionality. You can run the tests using npm:
npm run-script test-prod
The only difference between the test-prod and test-dev scripts is that the
development version includes source maps.
